Cycles: add GPU queue kernel time stats

* Print summary of kernel execution times for GPU queues with --verbose 3
* This is for combinations of kernels rather than individual ones, since
measuring individual ones has a performance impact.
* Refactor code to be independent of CUDA queue

Differential Revision: https://developer.blender.org/D11112

Cleanup: add mechanism for devices to not have a megakernel

Cleanup: move number of concurrent GPU paths to device queue

So different devices can set it to different values, though it's still
hardcoded as of now.

Fix wrong order of graphics interop destruction

The GPU display needs to be destroyed after path trace works, otherwise
the CUDA interop resource destruction will error with an invalid graphics
context.

Additionally, added guards to ensure the CUDA graphics interop object is
never copied.

Fix wrong number of integrator kernels

The value was off-by-one, causing buffer overflow on accessing the queue
counters.

Only apply edge panning in translation mode.

Longer edge pan delay and higher max speed.

Clean up comments.

Remove unused include.

[WIP] Compositor: Full-frame base system

This patch adds the base code needed to make the full-frame system work for both current tiled/per-pixel implementation of operations and full-frame.

Two execution models:
- Tiled: Current implementation. Renders execution groups in tiles from outputs to input. Not all operations are buffered. Runs the tiled/per-pixel implementation.
- FullFrame: All operations are buffered. Fully renders operations from inputs to outputs. Runs full-frame implementation of operations if available otherwise the current tiled/per-pixel. Creates output buffers on first read and free them as soon as all its readers have finished, reducing peak memory usage of complex/long trees.

This should allow us to convert operations to full-frame in small steps with the system already working and solve the problem of high memory usage.

FullFrame breaking changes respect Tiled system, mainly:
- Translate, Rotate, Scale, and Transform take effect immediately instead of next buffered operation.
- Any sampling is always done over inputs instead of last buffered operation.
